LUBRICANT-RECEPTACLE.

ratenteu may 1, 1906.

Application filed November 24, 1905. Serial No. 288,865.

T0 all whmn it may concern;

Be it known that I, WILLIAM T. RANDER- soN, a citizen of the United States of America, residing at Munhall, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lubricant-Receptacles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in lubricant-receptacles; and the invention relates more particularly to a novel form of grease-cup.

The primary object of this invention is to provide an inexpensive and simple greasecup adapted to be used in connection with journal-boxes or the like bearings where a shaft is to be lubricated or oiled.

Another object of this invention is the provision of novel means in connection with the grease-cup for agitating the contents of the cup and conveying the same to the shaft or element to be lubricated.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described and then specifically pointed out in the claims, and referring to the drawings accompanying this application like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a front elevation of my improved grease-cup. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a plan of the receptacle proper. Fig. 4 is a side elevation of the cup as mounted in a journalbox or bearing. Fig. 5 is a plan of a contact-head used in connection with the cup. Fig. 6 is a side elevation of a spring adapted to support said head.

To put my invention into practice I employ a metallic receptacle 1, the periphery of which is provided with spirallyarranged grooves forming threads 2. The receptacle is provided with a central depending stem 3, a portion of the stem adjacent to the receptacle being hexagonal in cross-section, as at 4, to permit of a wrench being placed thereon to permit of the cup being mounted in a journalbox or the like bearing. The remainder of the stem is tapered and provided with threads 4. The stem is provided with a verticallydisposed opening or bore 5, and the bottom In connection with the receptacle I use a metallic cap or cover 7, which is cylindrical in form and has its sides provided with spirallyarranged grooves forming threads 8, which are adapted to enga e the threads 2 of the re ceptacle 1. Central y of the top of the cap is secured a depending coiled spring 9, which extends downwardly through the receptacle 1 and the bore 5 of the stem 3 and is provided with a metallic tapering contact-block 10 upon its lower end, said block being circular in cross-section and having its sides provided with a groove 11, in which the end of the spring 9 is secured. The plug is preferably made of brass or the like durable material, While the cap 7 is preferably made of sheet metal, which is stamped to conform to the desired shape.

In Fig. 4 of the drawings I have illustrated a two-part journal-box 12, having a tapering opening 14, which leads to a shaft 15, journaled in the box 12. When the grease-cup is mounted in the opening 14 of the journalbox, the brass contact-block 10 of the cup is adapted to bear against the shaft 15, and as said shaft rotates it imparts avibratory movement to said spring. The spring in turn is adapted to agitate the grease or contents of the receptacle 1, causing the same to'percolate through the opening or bore 5 of the stem into the openin 14 of the journal-box, where it contacts wit the shaft 15 and thoroughly lubricates the same.

What I claim, and desire to secure by Letters Patent, is

1. An oil-cup embodying a receptacle, a screw-threaded stem carried by said receptacle and having a centrally-disposed bore formed therein, a cap adapted to fit upon said receptacle, a coiled spring carried by said cap and extending from within the receptacle through the said bore in the stem and below the end of the stem, a contact-block carried by said spring, the contact-block being disposed wholly below the end of the said stem, substantially as described.

2. A grease-cup embodying a receptacle, a centrally-disposed screw-threaded stem carried by said receptacle and having a centrallydisposed bore formed therein, a cap mounted upon sai eceptacle, a coiled spring carried by said cap and extending downwardly cap and extending downwardly through the through the bore of said stem, a tapering oonbore of said stern and below the end of the tactock carried by said spring, said taperstem, a removable contact-block carried by ing block being formed with a groove to resaid spring, said block being disposed wholly 15 5 ceive said spring, said block being disposed below the stem substantially as described.

wholly below the bottom of the stem sub In testimony whereof I afiix my signature stantially as described. in the presence of two witnesses.

3. A grease-cup embodying a receptacle, a WILLIAM T. RANDERSON. stem carried by said receptacle, said stem Witnesses: 10 having a bore formed therein, a cap mounted H. C. EVERT,

upon said receptacle, a spring carried by said E; E. POTTER.
